Open Stack

It's certainly something we're looking at (in Cisco) at the moment.  I
absolutely think it's worth having a session, though there are several
parts to the problem, and it crosses the nova-quantum divide which can make
it awkward to schedule:

- SR-IOV and directmap into the hypervisor (we're looking at Zardara
Storage's work on this with libvirt, which has never been incorporated into
the mainline but basically works fine)
- scheduling based on resources that are limited in number - that is,
scheduling to a machine that has remaining unallocated SRIOV NICs (or
whatever else)
- how one might get an SRIOV NIC into a Quantum network

And of course, not all devices that you might wish to directmap are NICs.

Migration's not something I've been giving much thought to, I admit.
